Struct TypedEvent 

pub struct TypedEvent<'a, E>
where
    E: Event,
{ /* private fields */ }

A typed view over an emitted event, combining topic access with a pre-decoded payload.

Implementations

impl<'a, E> TypedEvent<'a, E>

where E: Event,

pub fn new(raw: &'a TxEmittedEvent) -> TypedEvent<'a, E>

Decode a raw event into a typed view.

When E declares a static topic-0 discriminant (via Event::signature), the raw event’s topic 0 is verified against it first, so a payload that merely shares a shape with E cannot be silently mistyped as E. Panics on a discriminant mismatch, a topic count differing from Event::num_topics, or payload decode failure.

pub fn try_new(raw: &'a TxEmittedEvent) -> Option<TypedEvent<'a, E>>

Non-panicking twin of new: Some only if the event is well-formed, its topic 0 matches E’s declared discriminant (when one exists), its topic count matches Event::num_topics, and its payload decodes as E::Payload. The probe for scanning event streams that contain foreign events.

pub fn payload(&self) -> &<E as Event>::Payload<'a>

The decoded payload.

pub fn topic(&self, index: u32) -> Option<&'a [u8; 32]>

Get topic at the given index.

pub fn num_topics(&self) -> u32

Number of topics.

pub fn raw(&self) -> &EmittedEvent<'a>

Access the underlying untyped emitted event.
